Heavy Duty Door Magnet – Industrial-Grade Magnetic Door Contact Sensor
The Heavy Duty Door Magnet is a robust magnetic contact sensor designed to detect door openings in industrial and commercial environments. Built to endure high-impact use, this door contact is ideal for steel doors in factories, workshops, warehouses, garages, and other heavy-duty applications. Each sensor is normally closed (N.C.) by default and provides a reliable dry contact output. Its strong magnetic force and durable construction make it a dependable choice for securing heavy doors where standard latches or hinges are ineffective.
Product Features
Powerful Magnetic Force
This magnetic contact delivers exceptional holding strength, securely keeping large or heavy doors—such as barn doors, industrial gates, or commercial pantry doors—firmly closed. The compact dimensions (126 × 34.5 × 17 mm) allow discreet yet powerful installation.
Easy to Install and Position
Installation is quick and hassle-free. Simply anchor the magnet to the door frame and position the steel plate using the included adhesive strips. Once aligned, screw the plate in place for a permanent hold. Double-sided adhesive strips (colors may vary) simplify positioning before final installation.
Built for Harsh Environments
Crafted with 304-grade stainless steel, the housing resists corrosion, rust, and cracking. Designed to endure exposure to outdoor elements, moisture, or marine environments—making it suitable for kitchens, bathrooms, or industrial settings.
Reliable Sensor Output
Each unit comes pre-configured as Normally Closed (N.C.), offering consistent dry contact output suitable for integration with most wired alarm or monitoring systems.
Versatile Applications
This heavy-duty door magnet is ideal not only for secure closures but also as a magnetic tool holder for small metallic items. Suitable for use on steel doors, gates, lockers, cabinets, or mechanical enclosures.
